Attack-Flow Graph

Executive Summary

TinyEXIF before version 1.1.0 contains a heap-based buffer over-read vulnerability in the EntryParser::Fetch methods. This issue is triggered by a crafted SubjectArea length in an input file, which can lead to unintended memory access.

Detection Guidance

This vulnerability involves a heap-based buffer over-read in TinyEXIF before version 1.1.0, specifically in the EntryParser::Fetch methods due to a crafted SubjectArea length. Detection requires checking the installed version of TinyEXIF and inspecting files processed by it for malformed SubjectArea metadata.

Impact Analysis

This vulnerability may cause application crashes or unexpected behavior due to memory corruption. It could potentially allow information disclosure if exploited, though the impact is limited as it requires local access and has a low attack complexity.

Compliance Impact

This vulnerability does not directly impact compliance with GDPR, HIPAA, or similar standards. The issue is a low-severity heap-based buffer over-read in TinyEXIF that could lead to denial of service but does not involve data exposure or unauthorized access. Compliance risks would depend on how the affected software is used in a system handling regulated data.

Mitigation Strategies

Update TinyEXIF to version 1.1.0 or later to address the heap-based buffer over-read vulnerability in EntryParser::Fetch methods.
